Quantitative computed tomography is being increasingly used to quantify the features of
chronic obstructive pulmonary disease, specifically emphysema, air trapping, and airway …

Computed tomography has facilitated recognition that chronic obstructive pulmonary
disease is not a single disease but encompasses several overlapping entities, including …

Technical advances in medical imaging have provided an opportunity to examine the
airways of the lung more accurately than ever before. The aim of this article is to review the …

OBJECTIVE. The purpose of this study was to determine whether measurements of lung
attenuation at inspiration and expiration obtained from 3D lung reconstructions reflect the …

OBJECTIVE. The purpose of our study was to determine the attenuation threshold value for
the detection and quantification of air trapping using paired inspiratory and expiratory …

The severity of chronic obstructive pulmonary disease (COPD) is evaluated not only by
airflow limitation but also by factors such as exercise capacity and body mass index. Recent …

Chronic obstructive pulmonary disease (COPD) is characterized by the presence of airflow
obstruction caused by emphysema or airway narrowing, or both. Low attenuation areas …

Computed tomography (CT) is used to detect emphysematous changes in the lungs of living
patients. It is therefore important to develop a standard method for the radiographic …

Objectives To determine the relationship between lung function impairment and quantitative
computed tomography (CT) measurements of air trapping and emphysema in a population …

Purpose: To analyze the relationship between airflow limitation and airway dimensions from
the third to the fifth generation of bronchi in patients with chronic obstructive pulmonary …
